One United Nations Park

The tower rises 42 stories in a crisp black curtain wall — restrained, rigorously detailed, unmistakably Meier in proportion even as it departs from his usual white. The 148 condominium residences run from one to four bedrooms, including duplex and penthouse homes at the summit, all positioned on the upper floors to capture the river and skyline.

The interiors are finished to a high specification. Homes have white oak floors throughout; open kitchens feature white Calacatta Lincoln marble, Dornbracht fixtures, and Gaggenau appliances behind custom Italian white-lacquer cabinetry; and each residence is wired with a Crestron smart-home system controlling temperature, lighting, and motorized shades from a phone or tablet. The result is a contemporary, light-forward home that reads as architect-designed from the floor up rather than developer-standard.

One United Nations Park runs as a full-service condominium: a 24-hour attended lobby, doorman and concierge service, and a roughly 15,000-square-foot amenity suite designed by Richard Meier & Partners. The centerpiece is a 70-foot indoor lap pool with East River views, supported by a fitness center, sauna and steam room, yoga room, resident lounge, game room, a 12-seat screening room, and a children's playroom — furnished with pieces by Finn Juhl, Fritz Hansen, and Knoll. The condominium is pet-friendly. Common charges fund the staffing and amenity program and vary by residence size, running roughly in the low-to-mid four figures per month for typical homes and higher for the larger duplex and penthouse units. Pied-à-terre ownership is permitted; confirm financing, leasing and ownership-entity rules in the current declaration, bylaws and house rules.

Recent sales

Recent closings at this building, from The Roebling Research Library. Prices are the transfer amounts recorded with the NYC Department of Finance; apartment-level detail is checked against the building’s own file in The Roebling Research Library before publishing.

Market read. Most recent trades (2026 to date) cleared a median $1,703/sf (floor-adjusted) across 3 sales. Floor-adjusted means each sale is restated to a constant mix of floors, so the figure can differ from the plain median of the sales listed above. Median listing discount 20.2% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-00945-7502; each condominium apartment is its own tax lot). Apartment-level facts (line, condition, asking-price context) curated and cross-verified in The Roebling Research Library. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage from recorded condo declarations and offering plans.

Understand the two-building structure first. You are buying into the condominium portion at the top of the tower — the for-sale homes on the upper floors — which is governed and sold separately from the rental apartments below. That separation is to the buyer's benefit: the condominium residences hold the views and trade with condominium flexibility, while the rental floors carry their own operations.

Then weigh sponsor versus resale. With the sponsor still selling, much of the available inventory is new, immediate-occupancy product offered directly — which can mean negotiable concessions on price, common charges, or closing costs depending on the cycle, and a clean, well-documented offering plan to read. The condominium structure means no co-op board admission, and pied-à-terre ownership is permitted; confirm financing, leasing and ownership-entity rules in the declaration and bylaws. Buy the floor and the exposure: in a tower built around its views, altitude and river outlook are the value.

A resale here sells on scarcity and on the building's distinct identity: a Richard Meier–designed tower, a top-of-building condominium with full river and UN views, and a Meier-designed amenity suite anchored by a 70-foot lap pool. With sponsor inventory still in the market, the right strategy is to differentiate a resale clearly from new sponsor units — emphasizing a specific high floor, a finished and lived-in home, or a layout the sponsor no longer offers — rather than competing head-to-head on the sponsor's terms.

Benchmark to the building's own upper-floor trades and to the newest luxury condominium product near the UN and Midtown East, not to the surrounding rental or pre-war stock. Closing runs on condominium mechanics — a right-of-first-refusal rather than a co-op board process.
